Insights
Individualized antiplatelet therapy is crucial for preventing cerebral infarction. Platelet function testing (PFT) shows promise for optimizing antiplatelet treatment, reducing risks of stroke and bleeding.
Area of Science:
- Cardiology
- Neurology
- Pharmacogenomics
Background:
- Antiplatelet therapy is vital for secondary prevention of cerebral infarction.
- Drug resistance and excessive inhibition lead to ischemic or bleeding events, limiting clinical benefits.
- Current genetic testing (CYP2C19) is insufficient for managing these risks.
Purpose of the Study:
- To review the current evidence and application of Platelet Function Testing (PFT)-guided antiplatelet therapy for cerebral infarction.
- To explore PFT's potential in overcoming drug resistance and guiding de-escalation strategies.
- To identify variability in PFT application and suggest future research directions.
Main Methods:
- Review of current literature on PFT-guided antiplatelet therapy in cerebral infarction.
- Analysis of PFT's role in managing drug resistance and preventing ischemic/bleeding events.
- Examination of CYP2C19 genetic polymorphisms in relation to antiplatelet efficacy.
Main Results:
- PFT offers a direct measure of antiplatelet effects, potentially improving outcomes.
- While beneficial post-PCI, PFT's efficacy in cerebral infarction patients is debated.
- Significant variability exists in the current application of PFT for personalized antiplatelet regimens.
Conclusions:
- Platelet function testing holds promise for personalized antiplatelet therapy in cerebral infarction.
- Further research is needed to standardize PFT application and confirm its benefits in this patient population.
- Optimizing antiplatelet therapy through PFT can mitigate both ischemic and bleeding complications.
Abstract:
Current evidence indicates that antiplatelet therapy as a cornerstone for secondary prevention of cerebral infarction. However, ischemic or bleeding events arising from antiplatelet drug resistance or excessive platelet inhibition can diminish its clinical benefit. These challenges have laid the foundation for individualized antiplatelet treatment. Although cytochrome P450 family 2 subfamily C member 19 (CYP2C19) genetic polymorphisms have partially addressed the issue of drug resistance in these patients, they remain insufficient to resolve the high incidence of both ischemic and bleeding events. Platelet function testing (PFT)-guided antiplatelet therapy has been proven beneficial in patients after percutaneous coronary intervention, yet its efficacy in patients with cerebral infarction remains controversial. Platelet function provides a direct and comprehensive reflection of antiplatelet effects, offering potential not only to overcome drug resistance but also to guide de-escalation strategies, thereby mitigating the frequent occurrence of both ischemic and bleeding events in cerebral infarction. Overall, the current application of PFT to guide personalized antiplatelet regimens in patients with cerebral infarction is characterized by considerable variability. In light of recent advances in this field, we herein review the current landscape of PFT-guided individualized antiplatelet therapy in cerebral infarction, with the aim of summarizing existing evidence and offering suggestions for future research.
